Qatar Airways, for example, plans to resume Dreamliner service between Doha and London on May 15th, while United Airlines hopes to use the troubled jet for some Houston-Denver flights by May 31, five days earlier than the company had previously announced. Spokespeople are quick to clarify that these schedule changes are tentative, and entirely dependent on the FAA’s clearing the Dreamliner to fly.

Still, the news that airlines are adding Dreamliners back into their schedules at all suggests restored confidence that Boeing’s fix to the lithium batteries will be enacted and approved soon.
